SPARK-ARRESTER.

Specification of Letters Patent.

Patented Sept. 5, 1916.

Application led January 26, 1916. Serial No. 74,437.

To all whom t may concern.'

Be it known that I, SAMUEL B. KITCHIN, a citizen of the United States, residing at Scotland Neck, in the county of Halifax and State of North Carolina, have invented new and useful Improvements in Spark-Arrest ers, of which the following is a speciication.

The present invention relates to improvements in spark arresters for locomotives.

An object of the invention is to provide a simple, cheap and effective means whereby the products of combustion passing through the lire tubes of a boiler will, through the medium of the exhaust of a locomotive, be directed to a deector and from thence immersed in a body of liquid so that the smoke and other products of combustion will pass through the smoke stack in a cooled condition.

A still further object of the invention is to provide a. -spark arrester which will prevent live cinders passing through the smoke stack and wherein the draft from the lire box will not be interfered with.

With the foregoing objects in view and others which will appear as the nature of the invention is more fully understood the improvement resides in the construction, combination and operative arrangement of parts set forth in the following description and falling within the scope of the appended claim.

In the drawing, the figure illustrates a central vertical longitudinal sectional view through the boiler and re box of an ordinary locomotive.

In the drawing the numeral 1 designates the fire box, 2 the boiler having the longitudinally arranged lire tubes 3 that have their opposite ends supported in the boiler sheets 4.

The numeral 5 designates a casing which may be formed with or which may be connected to the boiler casing 2, the casing 5 being co-extensive of said boiler casing. This casing 5, at a suitable distance from the outer sheet L.Lis provided with a vertically arranged partition 6 the said partition being provided with a central opening to receive the flared end 7 of a longitudinally arranged pipe 8.

The pipe 8 terminates a suitable distance from the outer end of the casing 5 and this end of the said casing opposite the mouth of the tube 8 is arranged at an inward inclination as indicated by the numeral 9, said inv clined portion providing a deflector whereby llve cinders passing through the tube 8 will contact with the said surface 9 and be directed thereby to the bottom of the casing 5. The casing 5, is adapted to contain a quantity of liquid, indicated by the numeral 10 and if desired this liquid may reach a level below the center of the tube 8.

The numeral ll designates the ordinary exhaust pipe for the boiler, the said pipe extending vertically in the space 13 between the partition 6 and the sheet 4 of the boiler tube and has its end provided with a nozzle 14C that is arranged centrally of the flared mouth 7 of the directing tube 8.

The numeral l5 designates the smoke stack which 1s secured to the upper end of the partltion 5 at a suitable distance from the partition 6.

From the above description taken in connection with the accompanying drawing it will be noted that the live cinders will be forced by the exhaust passing through the nozzle 14 through the iiared mouth 7 of the directing tube 8, and as stated the same will contact with the deflector 9 causing the cinders to fall within the liquid l0 so that all the products of combustion will be permitted to pass through the stack l5 in a cooled condition. It will be further noted that by the particular construction and arrangement of parts the direct draft is not interfered with.

Having thus described my invention what is claimed is The combination with a boiler having a casing to support the front end thereof, aV

partition between the casing and the boiler, a tube having a liared end secured in the central opening in the partit-ion and extending longitudinally of the casing, the outer end of the casing opposite the tube being inclined to provide a. deflecting surface, a. liquid in the casing having its level arranged below the center of the tube, a stack for the cinders arranged adjacent to the partition, and the `exhaust pipe of the boiler having a nozzle disposed centrally in the flared end of the tube, as and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
